HSL standard element: for operating temperature below 70 ℃( instaneous 80℃ max.)
HSL-C element: for operating temperature below 100 ℃( instaneous 110℃ max.)
HSL filter element for surface filtration grant clean gas values of < 1 mg/m3, even with dusts of D50 < 1μm. The matrix consists of sintered polyethylene PE. An additional PTFE-coating gets into the pores of the PE-basic body and forms a micro-porous, non-sticking. This combined material is most extensively chemical resistant. The HERDING sinter plate filters are extremely stable in structure, rigid, water resistant and only need low-maintenance. The average useful life of HSL filter element can even exceed 10 years.
HSL filter element show a very high efficiency of separation and environmental compatibility. The filters can be recycled without any problems, no toxic waste has to be disposed off.
By using these filter elements in HSL-units there is an optimum combination of positive attributes like: compactness, optimum flow behavior, ideal dust emission and an extensive operational safety, resulting from the rigidity of the matrix and of no wear and tear against abrasive media. At regular intervals or at pre-determined differential pressure the filter elements are cleaned on-line by a jet-pulse.
The filter elements are fixed only by a single screw – which makes maintenance easy and saves times. On request antistatic or even special design, e.g. for using cooling lubricants or aerosoles are possible.
